FASTENING DEVICE.

SPECIFICATION forming part of Letters Patent No. 493,377, dat d March14, 1893.

Application filed Decembei- 31, 1892- Serial No. 456,974. (No model.)

To aZZ whom it may concern Be it known that I, MALCOLM FRISEN, a citizenof the United States, residing at Paterson, county of Passaic, and Stateof New Jersey, have invented certain new and usefulImprovements inFastening Devices; and I, do hereby declare the following to bea full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

This invention relates to a new and useful improvement in fasteningdevices and it is particularly applicable to fastening pins used insecuring tags to fabrics.

It consists in the improved construction whereby the point of thefastening device may be securely locked and easily disengaged from thebody of the pin, and it also consists in the novel construction andarrangement of parts hereinafter more fully set forth and claimed.

In the drawings Figure 1 is a side elevation of the improved fastenerwith price tag attached, showing the fastener locked. Fig. 2 is a topplan view of the fastener. Fig. 3 is an enlarged detailed view showingthe construction of the point and body of the pin whereby the same maybe locked into engagement with each other, and Fig. 4 is a verticalsection taken on the line :r-w of Fig. 1.

In the drawings a is the body of the pin made preferably of thin wire.The end I) of tween these flattened surfaces e and f is formed a ridgeg. The arms of the extreme point of the double curved portion 0 are bentinward to form a neck or contracted aperture h substantially as shown inFig. 4., This aperture h is snificiently wide to admit of the entranceof the point of the pinbut serves to bind upon and firmly hold the ridge9 when the pin is under a longitudinal strain.

It is manifest that this locking device is applicable to safety pins andsimilar fastening pins and that the essential feature ofthe presentinvention is a fastening pin having an enlargement g near its pointedend and at its other end a recess or slotinto which the point andenlargement are adapted to enter but which serves by its contractedaperture hbinding upon the enlargement g to retain the point within theslot when lateral or longitudinal strain is brought to bear upon thelocked pin.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A fastening device consisting of a strip of wire having at one end apoint and at the other end an opening formed by bending the wire backupon itself, the pointed end of said fastening device being flattened ator near the point in two planes approximately at right angles to eachother to form an enlargement, said enlargement being adapted to enterand be locked in the opening at the other end of the fastening device,substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this27th day of December, 1892.

MALCOLM FRISEN.
